New tools for R410A
Nes tools for R410A Chages
Gauge manifold
As the working pressure is high , it is impossible to measure the
working pressure using conventional gauges. In order to prevent
any other refrigerant from being charged,any other refrigerant
from being charged, the port diameters have been changed.
Charge hose
In order to increase pessure resisting strength, hose materials
and port sizes have been changed(to 1/2 UNF 20 threads
per inch).When puchasing a charge hose,be sure to confirm
the port size.
Electronic balance for refrigerant
charging
As working pressure is high and gasification speed is faft,
it is difficuit to read the indicated value by means of
charging cylinder ,as air bubbles occur.
Torque wrench (nominal dia.1/4,3/8)
The size of opposing flare nuts have been increased ,
incidentally,a common wrench is used for nominal
diameters 1/4 and 3/8.
Flare tooKclutch type)
By increasing the clamp bar'receiving hole size , strength
of spring in the tool has been improved.
Gauge for projection adjustment Used when flare is made by using conventional flare tool.
Vacuum pump adapter
Connected to conventional vacuum pump,it is necessary to use an adapter
to prevent vacuum pump oil from flowing back into the charge hose , The
charge hose connecting part has two ports-one for conventional refrigerant
(7/16 UNF 20 theads per inch )and one for R410A,if the vacuum pump oil (
mineraDmixes with R41OA a sludge may occur and damage the equipment.
Gas leakage detector Exclusive for MFC refrigerant
• lncidentally,the "refrigerant cylinder"comes with the refrigerant des i gnat ion (R410A)and
protector coating in the U.S's ARI specified rose color (Ari color code; PMS 507).
•Also the "charge port and packing for refrigerant cylinder"requires 1/2 UNF 20 theads per inch
corresponding to the charge pOse's port size.
